Astronomers have spotted the first ever "changing look" quasar. This gleaming object is located in deep space and appears to have its own dimmer switch. The finding could offer astronomers a glimpse at the history of these brilliant objects.
The intermittent light emitted from pulsars allows scientists to verify Einstein's theory of relativity. However, this theory could be analyzed more effectively if a pulsar with a black hole were found. Now, scientists have announced that this fact isn't the case in two particular instances.
Astronomers are getting a closer look at the gas cloud G2 in a galactic center that was originally discovered in 2011.
Astronomers may have just discovered a black hole that was ejected from a galaxy. The researchers have spotted a mysterious object that could either be a black hole, or a giant star that's exploding over an exceptionally long period of several decades.
A new mission may just discover hundreds of new black holes throughout the universe.
Astronomers may have found out exactly what a certain thin, bizarre object at the center of our galaxy might be. They've discovered that this object isn't a hydrogen gas cloud, but may instead be a pair of binary stars that is orbiting the black hole at the center of the Milky Way galaxy.
Massive black holes may just be blocking the formation of new stars in aging galaxies. Scientists have found that the radio-frequency-emitting particles that the black holes spew out can halt the creation of stars.
Scientists have long wondered whether matter is falling into the massive black hole in the center of our Milky Way galaxy, or being ejected from it. Now, scientists are searching for an answer.
Scientists have stumbled on a pulsating dead star shining with the energy of about 10 million stars. Called a pulsar, this dead star was previously thought to be a black hole because it was so powerful.
A certain black hole is more insatiable than expected. Astronomers have discovered a black hole that is consuming gas from a nearby star about 10 times faster than previously thought possible.
Scattered across the universe are some more mysterious black holes of an intermediate size and now, astronomers have gotten a closer look at one with the help of light pulses.
Scientists have found out that black holes may be more ravenous than expected. They've registered three possible occasions of the total destruction of stars by supermassive black holes at the centers of galaxies.
